[0116] The RedCap UE introduced in 3GPP Release 17 (R17) is mainly aimed at medium-speed applications. The maximum bandwidth of the RedCap UE under FR1 is 20MHz. In the related art, the applicable bandwidth of the RedCap UE is further reduced. The RedCap UE with further reduced bandwidth is called Enhanced RedCap UE.

[0117] Therefore, how to configure resources for enhanced Redcap UE using narrower bandwidth to achieve data communication with network-side devices is an urgent problem to be solved.

[0118] like Figure 2 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a base station of a cellular mobile communication system, including:

[0119] Step 201: Receive bandwidth capability information reported by a first type of capability-simplified user equipment UE, wherein the bandwidth capability information is at least used to indicate: a first bandwidth processing capability of the first type of capability-simplified UE, wherein the first bandwidth processing capability is less than or equal to a first bandwidth threshold, wherein the first bandwidth threshold is less than a second bandwidth threshold that can be supported by a second type of capability-simplified UE, wherein the first bandwidth processing capability is used to determine the maximum bandwidth that the first type of capability-simplified UE can allocate to a data channel.

[0120] In all embodiments of the present disclosure, the first type of simplified capability UE can report the type of the first type of simplified capability UE through bandwidth capability information, so that the base station side can know the first bandwidth processing capability and / or first bandwidth threshold of the first type of simplified capability UE.

[0121] The first type of capability-simplified UE may be an enhanced RedCap UE, which may be referred to as eRedCap UE for short.

[0122] The second type of simplified capability UE may be a RedCap UE in 3GPP Release 17 (R17). The bandwidth processing capability of the RF transceiver and baseband processing module of the second type of simplified capability UE in the FR1 (Sub-6GHz) frequency band is 20MHz. In a possible implementation, the maximum bandwidth that the second type of simplified capability UE can support is 20MHz.

[0123] The first type of simplified capability UE may have a lower baseband processing bandwidth and / or radio frequency processing bandwidth than the second type of simplified capability UE. In this way, the first type of simplified capability UE may save resources and power when performing data communication compared to the second type of simplified capability UE. In a possible implementation, the bandwidth processing capability (also referred to as the maximum bandwidth) that the second type of simplified capability UE can support is 5 MHz.

[0124] The first type of simplified capability UE can send bandwidth capability information to the base station during and / or after accessing the base station. Of course, the second type of simplified capability UE can send bandwidth capability information to the base station during and / or after accessing the base station.

[0125] The maximum bandwidth that can be allocated to the data channel by the first type of simplified capability UE may include but is not limited to: the maximum bandwidth that can be allocated to the data channel by the baseband of the first type of simplified capability UE.

[0126] The maximum bandwidth that the first type of capability simplifies the UE and can be allocated to the data channel may include but is not limited to: the maximum bandwidth that the first type of capability simplifies the UE and can be allocated to the data channel. Here, the data channel may include but is not limited to: a service data channel. The data channel can be used to transmit communication service data. Exemplarily, the data channel may include but is not limited to: a physical downlink shared channel (PDSCH, Physical Downlink Shared CHannel), and / or a physical uplink shared channel (PDSCH, Physical Uplink Shared CHannel).

[0127] The maximum bandwidth that the first type of capability simplifies the UE and can allocate to the data channel can be equal to the first bandwidth processing capability or less than the first bandwidth processing capability. Alternatively, the maximum bandwidth that the first type of capability simplifies the UE and can allocate to the data channel can be less than or equal to the first bandwidth threshold. The first bandwidth processing capability can be less than or equal to the first bandwidth threshold.

[0128] In one embodiment, the first bandwidth threshold is 5 MHz and the second bandwidth threshold is 20 MHz. For example, the bandwidth capability information may be used to indicate: a first bandwidth processing capability of a first-type capability simplified UE; wherein the first bandwidth processing capability is less than or equal to 5 MHz.

[0129] In all embodiments of the present disclosure, the bandwidth capability information may be the bandwidth value itself, a parameter for identifying the bandwidth value, or a parameter capable of determining the bandwidth value according to a preset method, which is not limited in the embodiments of the present disclosure. In the embodiments of the present disclosure, this will not be described one by one.

[0130] Exemplarily, the first bandwidth processing capability may be specified by the communication protocol. For example, the communication protocol may specify that the first bandwidth processing capability of the first type of simplified capability UE is 5 MHz. That is, the maximum bandwidth that the first type of simplified capability UE can allocate to the data channel is less than or equal to 5 MHz.

[0131] The first bandwidth processing capability may be specified by the communication protocol, reported by the UE to the base station, determined by the base station and then sent to the UE, or agreed upon by the base station and the UE. For example: the bandwidth capability information sent by the first-type capability-simplified UE may include an identifier or indicator for indicating the type of the first-type capability-simplified UE, so that the network side device can determine that the UE sending the bandwidth capability information is a first-type capability-simplified UE. In one possible implementation, when the network side device determines that the UE is a first-type capability-simplified UE through the bandwidth capability information sent by the UE, it can correspondingly determine the first bandwidth processing capability of the first-type capability-simplified UE.

[0132] The maximum bandwidth that can be allocated to the data channel by the first type of capability-simplified UE may include but is not limited to: the bandwidth that the baseband signal transmission path can transmit data, and / or the bandwidth that the baseband signal processing components such as the baseband processor can process data.

[0133] The base station may configure resources for the first type of capability simplification UE based on the bandwidth capability information reported by the first type of capability simplification UE. The bandwidth of the data channel resources configured by the base station for the first type of capability simplification UE may be less than or equal to the first bandwidth processing capability.

[0134] In this way, the first type of capability reduction UE indicates its own first bandwidth processing capability to the base station through bandwidth capability information, and the base station configures data channel resources for the first type of capability reduction UE. Thus, the first type of capability reduction UE can process data channels with a relatively smaller bandwidth processing capability than other types of UEs, thereby reducing workload and saving power.

[0135] In one embodiment, the bandwidth capability information may be used to indicate:

[0136] The first type of capability simplifies the second bandwidth processing capability of the UE, wherein the second bandwidth processing capability is less than or equal to a third bandwidth threshold; the second bandwidth processing capability is used to determine the maximum bandwidth received and / or sent by the UE simplified by the first type of capability.

[0137] The maximum receiving bandwidth of the first type of simplified capability UE may be the maximum bandwidth of the first type of simplified capability UE for receiving radio frequency signals. The maximum sending bandwidth of the first type of simplified capability UE may be the maximum bandwidth of the first type of simplified capability UE for sending radio frequency signals.

[0138] The maximum bandwidth received and / or sent by the first capability simplifies that the UE may be less than or equal to the second bandwidth processing capability. In some possible implementations of the present disclosure, the second bandwidth processing capability may be the sum of the maximum bandwidth for transmitting service data and the maximum bandwidth for transmitting control signaling.

[0139] The first type of capability simplifies the maximum bandwidth that the UE receives and / or sends, and may include: the maximum bandwidth that a radio frequency processing unit such as a transceiver antenna and a radio frequency processor can send and / or receive radio frequency signals.

[0140] The first category capability simplifies the maximum bandwidth received and / or sent by the UE: the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can monitor, and / or the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can receive, and / or the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can send.

[0141] In one embodiment, the third bandwidth threshold is greater than or equal to the first bandwidth threshold.

[0142] In one embodiment, the third bandwidth threshold is equal to or less than the second bandwidth threshold.

[0143] In all embodiments of the present disclosure, the bandwidth threshold of the first type of simplified capability UE can be further limited to a third bandwidth threshold that is less than the first bandwidth threshold (5 MHz), so as to further determine that the bandwidth processing capability of the first type of simplified capability UE is less than the first bandwidth threshold. This scenario can be used to further limit the bandwidth capability of the first type of simplified capability UE.

[0144] Or, in all embodiments of the present disclosure, the bandwidth threshold of the first type of simplified capability UE may be determined to be a third bandwidth threshold greater than the first bandwidth threshold (5 MHz) and less than or equal to the second bandwidth threshold (20 MHz), so as to limit the bandwidth processing capability of the first type of simplified capability UE to be greater than the first bandwidth threshold and less than or equal to the second bandwidth threshold. That is, in a possible implementation, it may be determined that the bandwidth capability of the first type of simplified capability UE is greater than 5 MHz and less than or equal to 20 MHz.

[0145] The maximum bandwidth received and / or sent by the first type of capability-simplified UE may be less than or equal to the second bandwidth threshold supported by the second type of capability-simplified UE, and greater than or equal to the first bandwidth threshold. In this way, the bandwidth capability of the first type of capability-simplified UE for receiving and / or sending can meet the transmission requirements of the first type of capability-simplified UE. For example, it meets the transmission requirements of the first type of capability-simplified UE data channel, and / or control channel, and / or reference signal, and / or synchronization broadcast block. The bandwidth capability information may indicate that the first bandwidth processing capability is less than or equal to the first bandwidth threshold, and the second bandwidth processing capability is less than or equal to the third bandwidth threshold. For example, the bandwidth capability information may indicate that the first bandwidth processing capability is 3MHz and the second bandwidth processing capability is 10MHz. Or the bandwidth capability information may indicate that the first bandwidth processing capability is 5MHz and the second bandwidth processing capability is 20MHz.

[0146] In one embodiment, the bandwidth capability information may be used to indicate at least one of the following:

[0147] The third bandwidth processing capability of the first type of capability simplifies the UE, wherein the third bandwidth processing capability is less than or equal to the first bandwidth threshold; or the third bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; the third bandwidth processing capability is used to determine the maximum bandwidth that the first type of capability simplifies the UE that can be allocated to the control channel. In all embodiments of the present disclosure, the third bandwidth processing capability can be exemplarily: the maximum bandwidth that the first type of capability simplifies can be allocated to the control channel.

[0148] The fourth bandwidth processing capability of the first-type capability-simplified UE, wherein the fourth bandwidth processing capability is less than or equal to the first bandwidth threshold; or the fourth bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; the fourth bandwidth processing capability is used to determine the maximum bandwidth that the first-type capability-simplified UE can allocate to the reference signal. In all embodiments of the present disclosure, the third bandwidth processing capability can be exemplarily: the maximum bandwidth that the first-type capability-simplified UE can allocate to the reference signal.

[0149] The fifth bandwidth processing capability of the first type of capability simplifies the UE, wherein the fifth bandwidth processing capability is less than or equal to the first bandwidth threshold; or the fifth bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; the fifth bandwidth processing capability is used to determine the maximum bandwidth that the first type of capability simplifies the UE can allocate to the synchronized broadcast block. In all embodiments of the present disclosure, the third bandwidth processing capability can be exemplarily: the maximum bandwidth that the first type of capability simplifies the UE can allocate to the synchronized broadcast block.

[0150] In all embodiments of the present disclosure, the bandwidth capability information can be used to indicate at least one of the following: a first bandwidth processing capability of a first type of capability-simplified UE, a second bandwidth processing capability of a second type of capability-simplified UE, a third bandwidth processing capability of a third type of capability-simplified UE, a fourth bandwidth processing capability of a fourth type of capability-simplified UE, and a fifth bandwidth processing capability of a fifth type of capability-simplified UE.

[0151] Exemplarily, in one scenario, the first type of capability-simplified UE can indicate the second bandwidth processing capability through bandwidth capability information, so that the network side device can know the sum of the maximum bandwidth used by the first type of capability-simplified UE to transmit service data and the maximum bandwidth used to transmit control signaling. And the first type of capability-simplified UE can also indicate the second bandwidth processing capability through bandwidth capability information, so that the network side device can know the maximum bandwidth used by the first type of capability-simplified UE to transmit service data. Then the network side device can determine the maximum bandwidth used by the first type of capability-simplified UE to transmit control signaling based on the first bandwidth processing capability and the second bandwidth processing capability.

[0152] The maximum bandwidth that the first type of capability simplification UE can allocate to the transmission control channel can be less than or equal to the third bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the third bandwidth processing capability can be equal to 5MHz, and the maximum bandwidth that the UE can allocate to the control channel can be 5MHz.

[0153] The maximum bandwidth that the first type of capability simplified UE can allocate to transmit reference signals can be less than or equal to the fourth bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the fourth bandwidth processing capability can be equal to 5MHz, and the maximum bandwidth that the UE can allocate to reference signals can be 5MHz.

[0154] The maximum bandwidth that the first type of capability simplifies the UE to allocate to the transmission synchronization broadcast block may be less than or equal to the fifth bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the fifth bandwidth processing capability may be equal to 5MHz, and the maximum bandwidth that the UE can allocate to the synchronization broadcast block may be 5MHz.

[0155] The control channel may be used to transmit communication control signaling. Exemplarily, the control channel may include, but is not limited to: a physical downlink control channel (PDCCH), and / or a physical uplink control channel (PUCCH), and / or a physical random access channel (PRACH). The maximum bandwidth that can be allocated to the control channel by the first type of capability simplification UE may be: the maximum bandwidth of the control signal transmitted by the first type of capability simplification UE using control channel resources.

[0156] Among them, the reference signal may be, but is not limited to, used for UE to perform channel measurement and / or synchronization. Exemplary reference signals may include, but are not limited to: a channel state information reference signal (CSI-RS, Channel State Information-Reference Signal), and / or a positioning reference signal (PRS, Positioning Reference Signal), and / or a channel sounding reference signal (SRS, Sounding Reference Signal). Exemplarily, the maximum processing bandwidth of the UE baseband for different channels and / or signals may be specified by the communication protocol.

[0157] The communication protocol specifies that the maximum processing bandwidth ranges for different channels and / or signals may be the same.

[0158] Exemplarily, the communication protocol may specify that the maximum bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel, reference signal and synchronization broadcast block is less than or equal to the first bandwidth threshold. For example, the first bandwidth threshold is 5MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel, reference signal and synchronization broadcast block is less than 5MHz.

[0159] The maximum processing bandwidth ranges for different channels and / or signals specified in the communication protocol may be different. For example, different processing bandwidths may be set for different service scenarios.

[0160] Exemplarily, in one configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to the first bandwidth threshold, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel and the control channel is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz.

[0161] Exemplarily, in another configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than or equal to the first bandwidth threshold; the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel, reference signal and / or synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information may indicate that the maximum baseband processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel and synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz.

[0162] The above only exemplifies several specific configurations that can be allocated to data channels, control channels, reference signals and synchronization broadcast blocks by the first type of capability simplification UE. Any configuration combination that satisfies the maximum bandwidth range that can be allocated to data channels, control channels, reference signals and synchronization broadcast blocks by the first type of capability simplification UE can be used as an implementation method of the first type of capability simplification UE configuration.

[0163] like Figure 3 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a base station of a cellular mobile communication system, including:

[0164] Step 301: Based on the bandwidth capability information, configure transmission resources for the first type of capability simplified UE;

[0165] Step 302: Send resource configuration information indicating the transmission resources to the first type of reduced-capability UE.

[0166] Step 301 and step 302 may be implemented separately or in combination with step 201 .

[0167] The base station may configure resources for the first type of capability simplification UE based on the bandwidth capability information. The bandwidth of the resources configured by the base station for the first type of capability simplification UE may be less than or equal to the bandwidth processing capability of the first type of capability simplification UE. Here, the bandwidth processing capability may include the first bandwidth processing capability to the fifth bandwidth processing capability.

[0168] The resource configuration information may also be predefined by the communication protocol. The resource configuration information may be stored in the storage of the UE. For example, the transmission resource of the synchronized broadcast block may be predefined, and the first type of capability simplified UE may determine the transmission resource of the synchronized broadcast block based on the predefined resource configuration information.

[0169] In this way, transmission resources are configured within the processing bandwidth range indicated by the bandwidth capability information to meet the bandwidth processing capability of the first type of capability-simplified UE. On the one hand, the first type of capability-simplified UE uses a relatively small bandwidth in transmission, saving transmission resources. On the other hand, the first type of capability-simplified UE can process service data with a smaller bandwidth, reduce workload, and thus save power.

[0170] In one embodiment, the resource configuration information is used to indicate at least one of the following:

[0171] The spectrum resources of the data channel, wherein the maximum bandwidth of the spectrum resources of the data channel is less than or equal to a first bandwidth threshold;

[0172] spectrum resources of a control channel, wherein the maximum bandwidth of the spectrum resources of the control channel is less than or equal to the first bandwidth threshold, or the maximum bandwidth of the spectrum resources of the control channel is greater than the first bandwidth threshold and less than or equal to a third bandwidth threshold;

[0173] A spectrum resource of a reference signal, wherein the maximum bandwidth of the spectrum resource of the reference signal is less than or equal to a first bandwidth threshold, or the maximum bandwidth of the spectrum resource of the reference signal is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold;

[0174] The spectrum resources of the synchronized broadcast block, wherein the maximum bandwidth of the spectrum resources of the synchronized broadcast block is less than or equal to the first bandwidth threshold, or the maximum bandwidth of the spectrum resources of the synchronized broadcast block is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold.

[0175] Resource configuration information can be used for, but is not limited to, scheduling spectrum resources, and can also be used for scheduling time domain resources, code domain resources, etc.

[0176] Different types of spectrum resources can be scheduled using different resource configuration information. For example, the resource configuration information for scheduling spectrum resources for data channels can be different from the resource configuration information for scheduling spectrum resources for control channels. Resource configuration information can also be used to schedule spectrum resources for different channels and / or signals at the same time. For example, resource configuration information can be used to schedule spectrum resources for data channels and spectrum resources for control channels at the same time.

[0177] The base station can configure spectrum resources of different channels and / or signals for the UE based on the bandwidth processing capability of the first type of capability-simplified UE. Reasonable combinations of spectrum resource bandwidths of data channels, spectrum resource bandwidths of control channels, spectrum resource bandwidths of reference signals, and spectrum resource bandwidths of synchronization broadcast blocks that meet the bandwidth processing capability of the first type of capability-simplified UE can be used as implementation methods for the base station to configure spectrum resources for the first type of capability-simplified UE.

[0178] Exemplarily, for a data channel, the maximum bandwidth that can be allocated to the first type of capability simplification UE may be less than or equal to the first bandwidth threshold. After the base station determines the maximum bandwidth that can be allocated to the first type of capability simplification UE, the spectrum resource bandwidth of the data channel configured for the first type of capability simplification UE may be less than or equal to the first bandwidth threshold, so as to comply with the maximum processing bandwidth of the first type of capability simplification UE.

[0179] Exemplarily, in one configuration, the maximum bandwidth that can be allocated to the data channel, the control channel, the reference signal and the synchronization broadcast block by the first type of reduced-capability UE is less than or equal to the first bandwidth threshold.

[0180] For this configuration, the base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be less than or equal to the first bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, the control channel, the reference signal, and the synchronization broadcast block.

[0181] For example, Figure 4 As shown, for example, the first bandwidth threshold is 5 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel, reference signal and synchronization broadcast block is less than 5 MHz. The base station may configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal and the spectrum resource bandwidth of the synchronization broadcast block to be less than 5 MHz.

[0182] Exemplarily, in one configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to the first bandwidth threshold, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than the first bandwidth threshold but less than or equal to the third bandwidth threshold.

[0183] In response to this configuration, the base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, and the spectrum resource bandwidth of the reference signal to be less than or equal to the first bandwidth threshold, and configure the spectrum resource bandwidth of the synchronization broadcast block to be greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, control channel, reference signal, and synchronization broadcast block.

[0184] For example, Figure 5 As shown, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information can indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel and reference signal is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz. The base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel and the spectrum resource bandwidth of the reference signal to be less than 5MHz, and configure the spectrum resource bandwidth of the synchronization broadcast block to be greater than 5MHz, but less than or equal to 20MHz.

[0185] Exemplarily, in another configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than or equal to the first bandwidth threshold; the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel, reference signal and / or synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold.

[0186] In response to this configuration, the base station may configure the spectrum resource bandwidth of the data channel to be less than or equal to the first bandwidth threshold, and configure the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, the control channel, the reference signal, and the synchronization broadcast block.

[0187] For example, Figure 6As shown, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information can indicate that the maximum baseband processing bandwidth that can be allocated to the data channel by the first type of capability simplified UE is less than 5MHz, and the maximum processing bandwidth that can be allocated to the control channel, reference signal and synchronization broadcast block by the first type of capability simplified UE is greater than 5MHz, but less than or equal to 20MHz. The base station can configure the spectrum resource bandwidth of the data channel to be less than or equal to 5MHz, and configure the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be greater than 5MHz, but less than or equal to 20MHz.

[0188] In one embodiment, the bandwidth span occupied by the spectrum resources of the data channel, and / or the spectrum resources of the control channel, and / or the spectrum resources of the reference signal, and / or the spectrum resources of the synchronized broadcast block in the frequency domain at the same time indicated by the resource configuration information is less than or equal to the third bandwidth threshold.

[0189] Since the second bandwidth processing capability of the first type of simplified capability UE is less than or equal to the third bandwidth threshold, that is, in the RF frequency domain resource bandwidth, the maximum bandwidth that the first type of simplified capability UE can process is less than or equal to the third bandwidth threshold.

[0190] Therefore, when the base station configures spectrum resources of the data channel, and / or spectrum resources of the control channel, and / or spectrum resources of the control channel, and / or spectrum resources of the synchronized broadcast block for the first type of capability simplified UE, at the same time, the bandwidth span occupied by the configured spectrum resources in the frequency domain is less than or equal to the third bandwidth threshold.

[0191] The bandwidth span is determined based on at least one lowest frequency resource and at least one highest frequency resource of the spectrum resources for data channel transmission, and / or the spectrum resources for the control channel, and / or the spectrum resources for the reference signal, and / or the spectrum resources for the synchronized broadcast block.

[0192] For example, the base station configures the first type of capability simplified UE to simultaneously monitor any number (such as two or more) of signals and / or channels, and the difference between the lowest frequency and the highest frequency occupied by the channels is less than or equal to the third bandwidth threshold. Here, the signal may include a synchronization broadcast block and / or a reference signal, etc., and the channel may include: a data channel, and / or a control channel, and / or a reference signal, etc.

[0193] In one embodiment, the resource configuration information is further used to indicate a partial bandwidth BWP configured for the UE, wherein the bandwidth of the BWP is less than or equal to a third bandwidth threshold.

[0194] The first type of capability may be specified by a communication protocol, etc. to simplify the radio frequency capability of the UE. The radio frequency capability may be a second bandwidth processing capability.

[0195] Exemplarily, the communication protocol may stipulate that the second bandwidth processing capability of the first type capability simplified UE is less than or equal to the third bandwidth threshold, that is, the maximum channel bandwidth (Channel Bandwith) of the first type capability simplified UE radio frequency is less than or equal to the third bandwidth threshold.

[0196] When the base station configures the BWP for the first type of simplified capability UE, the BWP may be configured to be less than or equal to the third bandwidth threshold, so that the radio frequency capability of the first type of simplified capability UE can be met.

[0197] like Figure 7 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a first-type capability simplified UE of a cellular mobile communication system, including:

[0198] Step 701: Report bandwidth capability information to the base station, wherein the bandwidth capability information is at least used to indicate: a first bandwidth processing capability of the first-type capability simplified UE, wherein the first bandwidth processing capability is less than or equal to a first bandwidth threshold, wherein the first bandwidth threshold is less than a second bandwidth threshold that can be supported by the second-type capability simplified UE, wherein the first bandwidth processing capability is used to determine the maximum bandwidth that the first-type capability simplified UE can allocate to a data channel.

[0199] It should be noted that, for the definition of the same parameter, the method on the base station side and the method on the user terminal UE side may be the same, and therefore will not be described in detail.

[0200] In all embodiments of the present disclosure, the first type of simplified capability UE can report the type of the first type of simplified capability UE through bandwidth capability information, so that the base station side can know the first bandwidth processing capability and / or first bandwidth threshold of the first type of simplified capability UE.

[0201] The first type of capability-simplified UE may be an enhanced RedCap UE, which may be referred to as eRedCap UE for short.

[0202] The second type of simplified capability UE may be a RedCap UE in 3GPP Release 17 (R17). The bandwidth processing capability of the RF transceiver and baseband processing module of the second type of simplified capability UE in the FR1 (Sub-6GHz) frequency band is 20MHz. In a possible implementation, the maximum bandwidth that the second type of simplified capability UE can support is 20MHz.

[0203] The first type of simplified capability UE may have a lower baseband processing bandwidth and / or radio frequency processing bandwidth than the second type of simplified capability UE. In this way, the first type of simplified capability UE may save resources and power when performing data communication compared to the second type of simplified capability UE. In a possible implementation, the bandwidth processing capability (also referred to as the maximum bandwidth) that the second type of simplified capability UE can support is 5 MHz.

[0204] The first type of simplified capability UE can send bandwidth capability information to the base station during and / or after accessing the base station. Of course, the second type of simplified capability UE can send bandwidth capability information to the base station during and / or after accessing the base station.

[0205] The maximum bandwidth that can be allocated to the data channel by the first type of simplified capability UE may include but is not limited to: the maximum bandwidth that can be allocated to the data channel by the baseband of the first type of simplified capability UE.

[0206] The maximum bandwidth that the first type of capability simplifies the UE and can be allocated to the data channel may include but is not limited to: the maximum bandwidth that the first type of capability simplifies the UE and can be allocated to the data channel. Here, the data channel may include but is not limited to: a service data channel. The data channel may be used to transmit communication service data. Exemplarily, the data channel may include but is not limited to: PDSCH and / or PUSCH.

[0207] The maximum bandwidth that the first type of capability simplifies the UE and can allocate to the data channel can be equal to the first bandwidth processing capability or less than the first bandwidth processing capability. Alternatively, the maximum bandwidth that the first type of capability simplifies the UE and can allocate to data transmission can be less than or equal to the first bandwidth threshold. The first bandwidth processing capability can be less than or equal to the first bandwidth threshold.

[0208] In one embodiment, the first bandwidth threshold is 5 MHz and the second bandwidth threshold is 20 MHz. For example, the bandwidth capability information may be used to indicate: a first bandwidth processing capability of a first-type capability simplified UE, wherein the first bandwidth processing capability is less than or equal to 5 MHz.

[0209] In all embodiments of the present disclosure, the bandwidth capability information may be the bandwidth value itself, a parameter for identifying the bandwidth value, or a parameter capable of determining the bandwidth value according to a preset method, which is not limited in the embodiments of the present disclosure. In the embodiments of the present disclosure, this will not be described one by one.

[0210] Exemplarily, the first bandwidth processing capability may be specified by the communication protocol. For example, the communication protocol may specify that the first bandwidth processing capability of the first type of simplified capability UE is 5 MHz. That is, the maximum bandwidth that the first type of simplified capability UE can allocate to the data channel is less than or equal to 5 MHz.

[0211] The first bandwidth processing capability may be specified by the communication protocol, reported by the UE to the base station, or sent to the UE after being determined with the base station, or agreed upon by the base station and the UE. For example: the bandwidth capability information sent by the first-type capability-simplified UE may include an identifier or indicator for indicating the type of the first-type capability-simplified UE, so that the network side device can determine that the UE sending the bandwidth capability information is a first-type capability-simplified UE. In one possible implementation, when the network side device determines that the UE is a first-type capability-simplified UE through the bandwidth capability information sent by the UE, it can correspondingly determine the first bandwidth processing capability of the first-type capability-simplified UE.

[0212] The maximum bandwidth that can be allocated to the data channel by the first type of capability-simplified UE may include but is not limited to: the bandwidth that the baseband signal transmission path can transmit data, and / or the bandwidth that the baseband signal processing components such as the baseband processor can process data.

[0213] The base station may configure resources for the first type of capability simplification UE based on the bandwidth capability information reported by the first type of capability simplification UE. The bandwidth of the data channel resources configured by the base station for the first type of capability simplification UE may be less than or equal to the first bandwidth processing capability.

[0214] In this way, the first type of simplified capability UE indicates the first bandwidth processing capability of the first type of simplified capability UE to the base station through the bandwidth capability information, and the base station configures the data channel resources of the first type of simplified capability UE. Therefore, the first type of simplified capability UE can use a relatively smaller bandwidth processing capability than other types of UEs to process data channels, reduce workload, and save power.

[0215] In one embodiment, the bandwidth capability information may be used to indicate:

[0216] The first type of capability simplifies the second bandwidth processing capability of the UE, wherein the second bandwidth processing capability is less than or equal to a third bandwidth threshold; the second bandwidth processing capability is used to determine the maximum bandwidth received and / or sent by the UE simplified by the first type of capability.

[0217] The maximum receiving bandwidth of the first type of simplified capability UE may be the maximum bandwidth of the first type of simplified capability UE for receiving radio frequency signals. The maximum sending bandwidth of the first type of simplified capability UE may be the maximum bandwidth of the first type of simplified capability UE for sending radio frequency signals.

[0218] The maximum bandwidth received and / or sent by the first capability simplifies that the UE may be less than or equal to the second bandwidth processing capability. In some possible implementations of the present disclosure, the second bandwidth processing capability may be the sum of the maximum bandwidth for transmitting service data and the maximum bandwidth for transmitting control signaling.

[0219] The first type of capability simplifies the maximum bandwidth that the UE receives and / or sends, and may include: the maximum bandwidth that a radio frequency processing unit such as a transceiver antenna and a radio frequency processor can send and / or receive radio frequency signals.

[0220] The first category capability simplifies the maximum bandwidth received and / or sent by the UE: the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can monitor, and / or the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can receive, and / or the first category capability simplifies the maximum bandwidth of the radio frequency signal that the UE can send.

[0221] In one embodiment, the third bandwidth threshold is greater than or equal to the first bandwidth threshold.

[0222] In one embodiment, the third bandwidth threshold is equal to or less than the second bandwidth threshold.

[0223] In all embodiments of the present disclosure, the bandwidth threshold of the first type of simplified capability UE can be further limited to a third bandwidth threshold that is less than the first bandwidth threshold (5 MHz), so as to further determine that the bandwidth processing capability of the first type of simplified capability UE is less than the first bandwidth threshold. This scenario can be used to further limit the bandwidth capability of the first type of simplified capability UE.

[0224] Or, in all embodiments of the present disclosure, the bandwidth threshold of the first type of simplified capability UE may be determined to be a third bandwidth threshold greater than the first bandwidth threshold (5 MHz) and less than or equal to the second bandwidth threshold (20 MHz), so as to limit the bandwidth processing capability of the first type of simplified capability UE to be greater than the first bandwidth threshold and less than or equal to the second bandwidth threshold. That is, in a possible implementation, it may be determined that the bandwidth capability of the first type of simplified capability UE is greater than 5 MHz and less than or equal to 20 MHz.

[0225] The maximum bandwidth received and / or sent by the first type of capability simplification UE may be less than or equal to the second bandwidth threshold supported by the second type of capability simplification UE, and greater than or equal to the first bandwidth threshold. In this way, the bandwidth capability of the first type of capability simplification UE for receiving and / or sending can meet the transmission requirements of the first type of capability simplification UE. For example, it can meet the transmission requirements of the data channel, and / or control channel, and / or reference signal, and / or synchronization broadcast block of the first type of capability simplification UE.

[0226] The bandwidth capability information may indicate that the first bandwidth processing capability is less than or equal to the first bandwidth threshold, and the second bandwidth processing capability is less than or equal to the third bandwidth threshold. For example, the bandwidth capability information may indicate that the first bandwidth processing capability is 3 MHz and the second bandwidth processing capability is 10 MHz.

In all embodiments of the present disclosure, the third bandwidth processing capability can be exemplarily: the maximum bandwidth that the first-type capability-simplified UE can allocate to the reference signal.

[0230] The fifth bandwidth processing capability of the first type of capability simplifies the UE, wherein the fifth bandwidth processing capability is less than or equal to the first bandwidth threshold; or the fifth bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; the fifth bandwidth processing capability is used to determine the maximum bandwidth that the first type of capability simplifies the UE can allocate to the synchronized broadcast block. In all embodiments of the present disclosure, the third bandwidth processing capability can be exemplarily: the maximum bandwidth that the first type of capability simplifies the UE can allocate to the synchronized broadcast block.

[0231] In all embodiments of the present disclosure, the bandwidth capability information can be used to indicate at least one of the following: a first bandwidth processing capability of a first type of capability-simplified UE, a second bandwidth processing capability of a second type of capability-simplified UE, a third bandwidth processing capability of a third type of capability-simplified UE, a fourth bandwidth processing capability of a fourth type of capability-simplified UE, and a fifth bandwidth processing capability of a fifth type of capability-simplified UE.

[0232] Exemplarily, in one scenario, the first type of capability-simplified UE can indicate the second bandwidth processing capability through bandwidth capability information, so that the network side device can know the sum of the maximum bandwidth used by the first type of capability-simplified UE to transmit service data and the maximum bandwidth used to transmit control signaling. And the first type of capability-simplified UE can also indicate the second bandwidth processing capability through bandwidth capability information, so that the network side device can know the maximum bandwidth used by the first type of capability-simplified UE to transmit service data. Then the network side device can determine the maximum bandwidth used by the first type of capability-simplified UE to transmit control signaling based on the first bandwidth processing capability and the second bandwidth processing capability.

[0233] The maximum bandwidth that the first type of capability simplification UE can allocate to the transmission control channel can be less than or equal to the third bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the third bandwidth processing capability can be equal to 5MHz, and the maximum bandwidth that the UE can allocate to the control channel can be 5MHz.

[0234] The maximum bandwidth that the first type of capability simplified UE can allocate to transmit reference signals can be less than or equal to the fourth bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the fourth bandwidth processing capability can be equal to 5MHz, and the maximum bandwidth that the UE can allocate to reference signals can be 5MHz.

[0235] The maximum bandwidth that the first type of capability simplifies the UE to allocate to the transmission synchronization broadcast block may be less than or equal to the fifth bandwidth processing capability. For example, the first bandwidth threshold is 5MHz, the fifth bandwidth processing capability may be equal to 5MHz, and the maximum bandwidth that the UE can allocate to the synchronization broadcast block may be 5MHz.

[0236] The control channel may be used to transmit communication control signaling. Exemplarily, the control channel may include but is not limited to: PDCCH, and / or PUCCH, and / or PRACH. The maximum bandwidth that the first type of capability reduction UE can allocate to the control channel may be: the maximum bandwidth of the control signal transmitted by the first type of capability reduction UE using control channel resources.

[0237] Among them, the reference signal can be used to transmit the reference signal. The reference signal can be, but is not limited to, used for UE to perform channel measurement and / or synchronization. Exemplary reference signals can include, but are not limited to: CSI-RS, and / or PRS, and / or SRS. Exemplarily, the maximum processing bandwidth of the UE baseband for different channels and / or signals can be specified by the communication protocol.

[0238] The communication protocol specifies that the maximum processing bandwidth ranges for different channels and / or signals may be the same.

[0239] Exemplarily, the communication protocol may specify that the first type of capability reduction UE can allocate at least one of the maximum bandwidths of the data channel, the control channel, the reference signal, and the synchronization broadcast block, and the maximum bandwidths of the data channel, the control channel, the reference signal, and the synchronization broadcast block that the first type of capability reduction UE can allocate are all less than or equal to the first bandwidth threshold. For example, the first bandwidth threshold is 5MHz. The bandwidth capability information may indicate that the maximum processing bandwidths of the data channel, the control channel, the reference signal, and the synchronization broadcast block that the first type of capability reduction UE can allocate are all less than 5MHz.

[0240] The maximum processing bandwidth ranges for different channels and / or signals specified in the communication protocol may be different. For example, different processing bandwidths may be set for different service scenarios.

[0241] Exemplarily, in one configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to the first bandwidth threshold, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel and the control channel is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz.

[0242] Exemplarily, in another configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than or equal to the first bandwidth threshold; the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel, reference signal, and synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information may indicate that the maximum baseband processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel and synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz.

[0243] The above only exemplifies several specific configurations that can be allocated to data channels, control channels, reference signals and synchronization broadcast blocks by the first type of capability simplification UE. Any configuration combination that satisfies the maximum bandwidth range that can be allocated to data channels, control channels, reference signals and synchronization broadcast blocks by the first type of capability simplification UE can be used as an implementation method of the first type of capability simplification UE configuration.

[0244] like Figure 8As shown, this exemplary embodiment provides an information transmission method, which can be executed by a first-type capability simplified UE of a cellular mobile communication system, including:

[0245] Step 801a: Receive resource configuration information from the base station, wherein the resource configuration information is used to indicate transmission resources for the first type of simplified capability UE, wherein the resource configuration information is determined by the base station based on the bandwidth capability information;

[0246] and / or,

[0247] Step 801b: Obtain the predefined resource configuration information.

[0248] Steps 801a and 801b may be implemented separately or in combination with step 701.

[0249] The base station may configure resources for the first type of capability simplification UE based on the bandwidth capability information. The bandwidth of the resources configured by the base station for the first type of capability simplification UE may be less than or equal to the bandwidth processing capability of the first type of capability simplification UE. Here, the bandwidth processing capability may include the first bandwidth processing capability to the fifth bandwidth processing capability.

[0250] The resource configuration information may also be predefined by the communication protocol. The resource configuration information may be stored in the storage of the UE. For example, the transmission resource of the synchronized broadcast block may be predefined, and the first type of capability simplified UE may determine the transmission resource of the synchronized broadcast block based on the predefined resource configuration information.

[0251] In this way, transmission resources are configured within the processing bandwidth range indicated by the bandwidth capability information to meet the bandwidth processing capability of the first type of capability-simplified UE. On the one hand, the first type of capability-simplified UE uses a relatively small bandwidth in transmission, saving transmission resources. On the other hand, the first type of capability-simplified UE can process service data with a smaller bandwidth, reduce workload, and thus save power.

[0252] In one embodiment, the resource configuration information is used to indicate at least one of the following:

[0253] The spectrum resources of the data channel, wherein the maximum bandwidth of the spectrum resources of the data channel is less than or equal to a first bandwidth threshold;

[0254] spectrum resources of a control channel, wherein the maximum bandwidth of the spectrum resources of the control channel is less than or equal to the first bandwidth threshold, or the maximum bandwidth of the spectrum resources of the control channel is greater than the first bandwidth threshold and less than or equal to a third bandwidth threshold;

[0255] A spectrum resource of a reference signal, wherein the maximum bandwidth of the spectrum resource of the reference signal is less than or equal to a first bandwidth threshold, or the maximum bandwidth of the spectrum resource of the reference signal is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold;

[0256] The spectrum resources of the synchronized broadcast block, wherein the maximum bandwidth of the spectrum resources of the synchronized broadcast block is less than or equal to the first bandwidth threshold, or the maximum bandwidth of the spectrum resources of the synchronized broadcast block is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold.

[0257] Resource configuration information can be used for, but is not limited to, scheduling spectrum resources, and can also be used for scheduling time domain resources, code domain resources, etc.

[0258] Different types of spectrum resources can be scheduled using different resource configuration information. For example, the resource configuration information for scheduling spectrum resources for data channels can be different from the resource configuration information for scheduling spectrum resources for control channels. Resource configuration information can also be used to schedule spectrum resources for different channels and / or signals at the same time. For example, resource configuration information can be used to schedule spectrum resources for data channels and spectrum resources for control channels at the same time.

[0259] The base station can configure spectrum resources of different channels and / or signals for the UE based on the bandwidth processing capability of the first type of capability-simplified UE. Reasonable combinations of spectrum resource bandwidths of data channels, spectrum resource bandwidths of control channels, spectrum resource bandwidths of reference signals, and spectrum resource bandwidths of synchronization broadcast blocks that meet the bandwidth processing capability of the first type of capability-simplified UE can be used as implementation methods for the base station to configure spectrum resources for the first type of capability-simplified UE.

[0260] Exemplarily, for a data channel, the maximum bandwidth that can be allocated to the first type of capability simplification UE may be less than or equal to the first bandwidth threshold. After the base station determines the maximum bandwidth that can be allocated to the first type of capability simplification UE, the spectrum resource bandwidth of the data channel configured for the first type of capability simplification UE may be less than or equal to the first bandwidth threshold, so as to comply with the maximum processing bandwidth of the first type of capability simplification UE.

[0261] Exemplarily, in one configuration, the maximum bandwidth that can be allocated to the data channel, the control channel, the reference signal and the synchronization broadcast block by the first type of reduced-capability UE is less than or equal to the first bandwidth threshold.

[0262] For this configuration, the base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be less than or equal to the first bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, the control channel, the reference signal, and the synchronization broadcast block.

[0263] For example, Figure 4 As shown, for example, the first bandwidth threshold is 5 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel, reference signal and synchronization broadcast block is less than 5 MHz. The base station may configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal and the spectrum resource bandwidth of the synchronization broadcast block to be less than 5 MHz.

[0264] Exemplarily, in one configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to the first bandwidth threshold, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than the first bandwidth threshold but less than or equal to the third bandwidth threshold.

[0265] In response to this configuration, the base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel, and the spectrum resource bandwidth of the reference signal to be less than or equal to the first bandwidth threshold, and configure the spectrum resource bandwidth of the synchronization broadcast block to be greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, control channel, reference signal, and synchronization broadcast block.

[0266] For example, Figure 5 As shown, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information can indicate that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel, control channel and reference signal is less than 5MHz, and the maximum processing bandwidth that the first type of capability simplified UE can allocate to the synchronization broadcast block is greater than 5MHz, but less than or equal to 20MHz. The base station can configure the spectrum resource bandwidth of the data channel, the spectrum resource bandwidth of the control channel and the spectrum resource bandwidth of the reference signal to be less than 5MHz, and configure the spectrum resource bandwidth of the synchronization broadcast block to be greater than 5MHz, but less than or equal to 20MHz.

[0267] Exemplarily, in another configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of capability simplified UE can allocate to the data channel is less than or equal to the first bandwidth threshold; the maximum processing bandwidth that the first type of capability simplified UE can allocate to the control channel, reference signal and / or synchronization broadcast block is greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold.

[0268] In response to this configuration, the base station may configure the spectrum resource bandwidth of the data channel to be less than or equal to the first bandwidth threshold, and configure the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be greater than the first bandwidth threshold, but less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of capability simplified UE can process the data channel, the control channel, the reference signal, and the synchronization broadcast block.

[0269] For example, Figure 6 As shown, the first bandwidth threshold is 5MHz, and the third bandwidth threshold is 20MHz. The bandwidth capability information can indicate that the maximum baseband processing bandwidth that can be allocated to the data channel by the first type of capability simplified UE is less than 5MHz, and the maximum processing bandwidth that can be allocated to the control channel, reference signal and synchronization broadcast block by the first type of capability simplified UE is greater than 5MHz, but less than or equal to 20MHz. The base station can configure the spectrum resource bandwidth of the data channel to be less than or equal to 5MHz, and configure the spectrum resource bandwidth of the control channel, the spectrum resource bandwidth of the reference signal, and the spectrum resource bandwidth of the synchronization broadcast block to be greater than 5MHz, but less than or equal to 20MHz.

[0270] In one embodiment, the bandwidth span occupied by the spectrum resources of the data channel, and / or the spectrum resources of the control channel, and / or the spectrum resources of the reference signal, and / or the spectrum resources of the synchronized broadcast block in the frequency domain at the same time indicated by the resource configuration information is less than or equal to the third bandwidth threshold.

[0271] Since the second bandwidth processing capability of the first type capability simplified UE is less than or equal to the third bandwidth threshold, that is, the maximum bandwidth that the first type capability simplified UE can process in the radio frequency domain resource bandwidth is less than or equal to the third bandwidth threshold.

[0272] Therefore, when the base station configures spectrum resources of the data channel, and / or spectrum resources of the control channel, and / or spectrum resources of the control channel, and / or spectrum resources of the synchronized broadcast block for the first type of capability simplified UE, at the same time, the bandwidth span occupied by the configured spectrum resources in the frequency domain is less than or equal to the third bandwidth threshold.

[0273] The bandwidth span is determined based on at least one of the lowest frequency resource and at least one of the highest frequency resource of the spectrum resources of the data channel transmission, and / or the spectrum resources of the control channel, and / or the spectrum resources of the reference signal, and / or the spectrum resources of the synchronous broadcast block.

[0274] For example, the base station configures the first type of capability simplified UE to simultaneously monitor any number (such as two or more) of signals and / or channels, and the difference between the lowest frequency and the highest frequency occupied by the channels is less than or equal to the third bandwidth threshold. Here, the signal may include a synchronization broadcast block and / or a reference signal, etc., and the channel may include: a data channel, and / or a control channel, and / or a reference signal, etc.

[0275] In one embodiment, the resource configuration information is further used to indicate a partial bandwidth BWP configured for the UE, wherein the bandwidth of the BWP is less than or equal to a third bandwidth threshold.

[0276] The first type of capability may be specified by a communication protocol, etc. to simplify the radio frequency capability of the UE. The radio frequency capability may be a second bandwidth processing capability.

[0277] Exemplarily, the communication protocol may stipulate that the second bandwidth processing capability of the first type capability simplified UE is less than or equal to the third bandwidth threshold, that is, the maximum channel bandwidth (Channel Bandwith) of the first type capability simplified UE radio frequency is less than or equal to the third bandwidth threshold.

[0278] When the base station configures the BWP for the first type of simplified capability UE, the BWP may be configured to be less than or equal to the third bandwidth threshold, so that the radio frequency capability of the first type of simplified capability UE can be met.

[0279] A specific example is provided below in combination with any of the above embodiments:

[0280] According to the related technologies, it is required to further reduce the UE bandwidth to obtain eRedCap UE based on FR1 RedCap UE.

[0299] Method 3:

[0302] A processing bandwidth / maximum channel bandwidth of the terminal at a radio frequency (RF) is less than or equal to a second threshold.

[0303] The spectrum resources occupied by the base station for each data channel are not greater than the first threshold.

[0304] The base station may allocate resources to the synchronization broadcast block, the control channel, and / or the reference symbol that are greater than the first threshold but less than or equal to the second threshold.

[0305] The bandwidth of spectrum resources occupied by the BWP configured by the base station for the terminal is not greater than the second threshold.
